EUROVACThe Eurovac NV leak detector for vacuum systems is a class 1 leak detector according to EN 13160-1. The Eurovac HV leak detector may only be used to detect leaks in tanks which are not pressurised (i.e. operated under atmospheric conditions) and which are used for the storage of liquids. Eurovac NV is equipped with an output relay to transmit the alarm signal to additional external devices. If no error condition is present, the relay is de-energised. In the case of an alarm, the relay is energised.
